SPI Calibrated SEM Mounts

For the ultimate in built in documentation of magnification calibration

The ultimate mount for documenting magnification! We take a piece of pure silicon - the highest grade available (used for making electronic microcircuit chips) - then carefully etch in a lattice calibration grid, pattern, using the very latest electron beam lithography techniques. The etched chip is then firmly mounted into a precision machined aluminum SEM mount, available in a variety of styles to suit just about any SEM of any manufacturer.

Ideal for documenting the entire area containing particles, these calibration mounts also have sufficient surface area to support larger samples while still providing magnification documentation. Best for use when calibrating at one magnification.

Here's another plus: SPI Calibrated SEM Mounts are reusable! A "quick" swab with acetone will clean the surface free of most sample residues; somewhat more vigorous rubbing would remove more adherent particles. The real question at this point is, will a more vigorous rubbing with a Q-Tip^® and acetone cause damage to the silcon wafer and the checkerboard pattern? Well vigorous cleaning can put some scratches at some point, on the surface, the most deliterous effect of that being that such scratches could affect the way instruments doing an automated analysis perceive the pattern. So the bottom line is this: The pattern is etched into silicon so from the standpoint of something being fragile, we can assure you that the silicon chip is quite "robust". But you can be sure that if you rub hard enough and long enough, you will start to impart microscratches which then become bigger scratches.

Features:

Orthogonal repeat units of 10 µm
"Bars" that are 2.2 µm +/- 5% in width, more or less.
Easily cleaned for reuse with a good solvent (e.g. acetone) and a non-linting foam swab

But just remember, we can not guarantee the above mentioned dimensions and variance information but we really do believe that these numbers are either right on the mark or are very close to the reality of the samples. Measurements of the 10 µm repeat would suggest a "3 sigma" from different locations on the total wafer produced to be less than 0.100.
